Wind-breaker for lanterns



UNITED STATES PATENT OFFICE.

ABRAMDAVIS, OF CHICAGO, ILLINOIS.

IWIND-BREAKER FOR LANTERNS.

.To LZZ whom, it may concern.-

Be it known that l, ABRAM DAVIS, of Ohicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvemcnts inWind-Breakers for the Top and Bottom of Lanterns and Lamps; and I dohereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, and letters ofreference marked thereon, and which forms part of this specication, thegure being a vertical section of a lantern full size.

The nature of my invention consists in providing the usual tops oflanterns and lamps with wind-breaker c c c c, that will effectuallyprevent currents of air from striking the name and causing smoke andextinguishing it, and at the bottom with wind-breaker h h h h, whichwill prevent currents of air from striking the liame and producing smokeand extinguishing it, as usually occurs when kerosene and other oils areburned in strong currents of air.

To enable others skilled in the art to make and use my invention7 I willproceed to describe its construction and operation.

I construct my lanterns or lamps in any of the usual forms, and applywind-breakers, as hereinafter described.

The ligure is a vertical section of a handlantern with wind-breakersapplied.

A represents the bottom or foot of the lantern.

B represents the top or head.

Wind-breaker c c c c in the top of the lantern, of any suitablematerial, I make by uniting the frusta of two cones 0f greater or lessacuteness, as the diameter and height of top may require. It may also bemade by Hanging the top of a conical or straight tube; but I prefer theformer. The base of this wind-breaker is made to iit the top band, d,and its top about three-eighths of an inch less in diameter, and thusleave about threesixteenths (T) of an inch space around itscircumference between it and the top band, d, and about one-fourth of aninch below the close top e, for the passage of smoke and heated air, asindicated by arrow No. 2. The perforations in the top band, d, should beoneeighth of an inch or more below the top of the Wind-breaker.

Arrow l indicates the passage of air-currents through the perforationsin top band, d,

and around the concavity of the wind-breaker and escaping at theopposite side.

f is a perforated top over the close top e, as a guard for the handagainst excessive heat.

The bottom wind-breaker, h it h h, is a band of tin or any othersuitable metal or glass, with a iange at its base, and set in the bottomband, G, below the usual perforations, and sufficiently wide to turnthecurrent of air between the wind-breaker and bottom band up into thechamber of the globe I, as indicated by arrow 3, and thus guard the amefrom sudden blasts and excessive currents,- which would produce smokeand extinguish the ilam e. The diameter of this wind-breaker should beabout three-eighths of an inch less than the bottom of the globe, thusleaving about three-sixteenths (T35) of an inch space around its top forthe passage of air to the chamber above, and any excess passing offthrough the top.

Arrow 4 indicates the natural current of air through the perforations ofthe bottom band, G, over the wind-breaker, and down through theperforations of the keroseneburner L to support the flame.

If glass is used for this wind-breaker, it may be made wider'and extendhigher into the globe or lantern without obstructing the light, and whenit is made of metal it may be perforated; but I prefer it without.

I usually construct my wind-breakers as above described, varying inproportion to the size and form of the lantern or lamp.

Having thus fully described my invention, what I claim isy 1. Thewind-breaker c c c c for the top of lanterns and lamps, made of anysuitable material by uniting the frusta of two cones or theirequivalents, which will cause currents of air to pass around theirconcavities. and escape at the opposite side without disturbing orextinguishing the flame, as described.

2. The wind-breaker h h 7i h, which is a band made of tin or any othersuitable metal or of glass, with a flange at its base, and set in thebottom band below the perforations, which will turn the current of airup into the chamber above and prevent extinguishing the dame, asdescribed, and for the purposes specified.

ABRAM DAVIS.
